A heat exchanger is a device that is used for thermal energy exchange. It may be within the solid or solid fluid interface or within the gas itself having temperature gradient. Heat exchanger are vital from industry point of view having good efficiency and also having an economic running cost. Study is been conducting on enhancing the heat transfer rate. The paper proposes the research and practical work done on dimple tube heat exchanger which is a heat transfer augmentation technique.

Keywords: Thermal energy exchange, Temperature gradient, Heat transfer augmentation.
